It is very important that every part of the axle-blank be improved b being 4o worked, and it. is on that account t at the blank is inclosed by the dies. This condition necessitates the first, swelling action throughout the entire blank caused hynn earlyr com tact with the hendingdie, cud rcsultin in' 45 the blank quickly being firmly griispe at oints in the stationar and movalile dies, after which the genera upsetting cruised by the frictioncl draggin action at the above places of contact of t ie movable dies upon 5o the bar or billet'will take place In forgin i articles that lmve two forged ends-an ax e, for example---I prefer to use in connection .with a sin le stationary holdingdie two sets of movnb c dies one-set for enclr 55 end'of thc lmr, similar memliers of both sets of dies operating simultaneously toward the i is die-closer operated hydraulically nja well-known manner through n piston jnnd xsf cglindcr 1:.

parts'o the dies not first in engagement therewith. The metal between the station-` 15 ary and movable dies will upset to form a fin n, Fig. 3,' and as this fin may sometimes be so large as to prevent the complete approachment between the movable and stationary dies I place at the forward end of the movzo able dies a shear o, which as this latter die advances cutsof` the fin. Upon the last stroke oli-the upsetting action when the dies are to be completely filled and shoulders made the friction between the metal and the 2 5 inside walls of the upsetting-dies becomes so great that the metal, seekin f the lines of least i resistance, will bulre out ctwecn the .stational'y and mova le dies and Ipresently bring the movable die toa comp ete stop. 3o `,In orderto prevent this, the shear o is em- "-ployed to undercutWthe fin, whichwill per- M Init4 the movable die to complete its stroke,

shearing and'up'setting taking place simultaneously. 35 p is a header-die which after the inner fpart of the bar has been upset is driven in to crm the head upon the bar.

The dies d p may be actuated in any suit- ,ablemannelz In the drawings I have shown' '4o a hydraulic arran ement for actuating them consisting of a ho low iston r, which is carried in a cylinder s 'andhal piston t, carried by andI working in the hollow piston r. The

piston .r is first actuatedJ carrying the piston t along with it, thus drivin in the dies d and 45 p\ simultaneously, and a ter this die has wholly or partly completed its stroke the piston t is. actuated separately to drive in the eader-die p to form the head upon the end of the bar. 4

u is the pipe for admittingthe actuating' liquid or gas to cylinder s, and 'u is the ipe for admitting the actuating liquid to the ol` low piston r. 4 In an application forPatent of the.United 5 5 States bearin even date herewith 4I have described in c etail the construction of the dies and, thc means for operating them.

Having thus described my invention, I claim as new and desire to secure by Letters 1. The described method of upsetting a bar or billet which consists in first inclosing the bar or billet in dies longitudinally separable, causing saiddics to approach one another and simultaneously applying end pressure to the bar to cause the metal to nieve with the dies thus swelling the metal within and. between them, continuing the approachment of and completing the upsetting ofthe metal within and between the dies; and finally u setting the end of the bar while held within the said dies.

2. The described method for upsetting a -bar or billet, which .consists in first inclosing the 75 bar or billet in dies longitudinally separable; secondly, moving said dies toward one" another andl causing the metal to move with' said dies in'order to u setthe metal Within and between them, andl finally upsettingthe 8o end of the bar while held within said-dies.
